A systematic study is currently demonstrated approach for approving the superior role of silver and palladium metallic particles in acting the role of mordant with acquiring the dyed cotton fabrics excellence in color fastness with additional functions of antimicrobial potentiality and UV-protection action. Whereas, samples were dyed with extract of red peanuts skin as natural textile colorant (RPN dye). The represented data revealed that, in absence of mordant, the samples treated with metal precursors prior to dyeing were exhibited with the excellent color strength, color fastness, antimicrobial action and UV-protection action. Color fastness (washing, rubbing and light fastness) was estimated to be in the range of very good-excellent. Sample pretreated with silver salt and dyed in the absence of mordant was graded with excellent UV-protection action (UPF 31.5, UVB T% 2.6% and UVB blocking percent 97.4%). Antimicrobial potency against E. coli, S. aureus and Candida albicans through inhibition zone and the reduction percent was approved to be in the range of excellence (93.01-99.51%) for the samples dyed in absence of mordant and pretreated with either silver or palladium precursors.
目前，系统研究表明，银和钯金属颗粒在作为媒染剂方面的卓越作用是通过获得染色棉织物在色牢度方面的优异性能，以及额外的抗菌潜力和 UV 防护作用来证明的。而采用红花生皮提取物作为天然纺织染料（RPN 染料）对样品进行染色。所呈现的数据表明，在没有媒染剂的情况下，金属前体处理过的样品在染色前就表现出优异的颜色强度、色牢度、抗菌作用和 UV 防护作用。色牢度（耐洗、耐摩擦和耐光）被评估为非常好-优秀。在没有媒染剂的情况下用银盐预处理并染色的样品被评为具有优异的 UV 防护作用（UPF31.5、UVB T%2.6%和 UVB 阻断率 97.4%）。通过抑菌圈和减少百分比，未经媒染剂染色且用银或钯前体制备的样品对大肠杆菌、金黄色葡萄球菌和白色念珠菌的抗菌效力被证实为优秀（93.01-99.51%）。
